Primary cladding is made of UV – resistant material (Acrylate), minimizing environmental effects
Primary cladding has nominal diameter of 245mm ± 10mm before coloring and 250mm ± 10mm after coloring, using permanent ink.
During welding, primary cladding can easily be separated from fiber without using chemicals and affecting the fiber
